Laughing From the Mountaintop

My Technology in Literature class wrapped up discussion of HG Wells’ The Time Machine recently. Every time I read the work, the thing that most interests me is the simple explanation the Time Traveler gives at the very beginning regarding the feasibility of time travel. In essence, he suggest that we already do travel in time–when we remember something or dream of things past–but we cannot remain for any period of time. Thus, we are as constrained in travel in the fourth dimension just as primitive man was in the third (i.e. you can jump up and down or fall of a cliff, but you can’t remain or travel freely through the dimension of height without the assistance of technology).

Wells envisions the solution to this problem pretty simply–the Time Machine works rather like a railroad engine. It can go forward and in reverse, it has a throttle and brakes, and the ‘engineer’ manipulates the whole process with a pair of simple levers. On the whole, it seems even less complicated than driving a car.

Many have been the time-travel tales since then. However, we have envisioned the process differently. One does not

Some theories of time travel are more plausible than others...

travel through time in the same way as we walk down the street or fly to Atlanta; the devices involve some kind of sudden leap or jolting transference. The process is instantaneous, or nearly so. We go there in Deloreans or weird tubes (12 Monkeys) or telephone booths or even hot tubs. I sort of doubt, however, that time travel (assuming it’s possible) would work that way. I kinda think that Wells, for all his antiquity, had the better theory.

Consider this: How has all travel, thus far, functioned? Air, sea, space, or land, we move progressively across space. Now, granted, that’s space, and we’re talking time. Time, though, isn’t supremely different than space. We can’t define what makes up space anymore than we can time (ask a physicist sometime about ‘what space is made of’ and get ready for some weird, mostly theoretical stuff). The primary difference, though, is that we are better able to perceive of space than we are time. Perhaps, for this reason, time travel is beyond us–we just aren’t smart enough to ‘see’ it as it is.

Not a Straight Line

The average person on the street sees time as an arrow–we proceed from point A to point B along the minutes and the hours and so on. This is why time-travel stories are so concerned about ‘altering the past to destroy the future’. We are, arrogantly, considering time to be a single path of causality and that, if we change something back then, then we will necessarily alter something right now. Time, though, isn’t a line or an arrow. It’s a dimension, like width, depth, and height. If you could travel through time, you could go sideways as well as back and forth. You could even, perhaps, look at time from a different direction.

The Mountaintop of Boethius

Oddly enough, much of my knowledge of theoretical physics has been supported by existential philosophy, and vice versa. I don’t claim to be an expert in either, but I can readily see the connections. Thus, my reading of The Consolation of Philosophy in my freshman-year western culture seminar fundamentally changed my perception of what time travel might consist of.

In this work, there is a part where Philosophy is trying to explain to Boethius how it is that God can be omniscient while, at the same time, mankind can be given free will. I don’t have the text in front of me right now, but in summation, Boethius asks how it could be that all of his actions and the results of these actions could be known to God and, yet, he might still have command over what he does. Couldn’t he then do something God didn’t expect and upset the whole divine apple-cart?

Philosophy’s answer goes like this: God is not part of the flow of time as Boethius or, indeed, as any mortal sees it. God looks upon the world from a mountaintop, and beneath Him is spread all that Was, Will Be, and Is, existing for Him as a kind of eternal Present. He is able to perceive of all time simultaneously. Thus, He can look down at what any one person is doing now, see how it relates to what they have done, and then see how it will lead to what they will do. Presumably, when taking quantum physics into account here, God would be able to see the outcomes of all possible outcomes of all possible actions, viewing them simultaneously, and thus be omniscient without really interfering with an individual’s decision-making process. This idea is echoed in Grendel’s discussion with the Dragon in Gardner’s Grendel, as well as the Architect of The Matrix: Reloaded.

How does this connect to time travel? Well, it makes the device needed to make it happen both monstrously more complex than any other we’ve seen, but also simpler in operation. All that is needed is to be able to see time as it is–as a kind of dimension across which we may travel in any direction–and then make the machine go there. It’s not an instantaneous jump or a lightning-bound explosion, it’s more like a stroll down from a mountain.

The thing is, though, it’s the kind of stroll only a God seems to be able to make.
